Question

there were m visitors in an exhibition on the first day and 1200 fewer visitors on the second day. On the third day the number of visitors was 30%:greater than the number of visitors on the second day. What was the average number of visitors over the 3 days

Answer 1

first day: m

second day: m - 1200

third day: (m - 1200)(1.30)

 

[m + (m - 1200) + (m -1200)(1.30)] / 3

 

Can you determine the average?
